ID:KI18B_HUMAN DESCRIPTION: RecName: Full=Kinesin-like protein KIF18B; FUNCTION: In complex with KIF2C, constitutes the major microtubule plus-end depolymerizing activity in mitotic cells. Its major role may be to transport KIF2C and/or MAPRE1 along microtubules. SUBUNIT: Interacts with MAPRE1; this interaction is required for efficient accumulation at microtubule plus ends. Interacts with KIF2C at microtubule tips; this interaction increases the affinity of both partners for microtubule plus ends and is required for robust microtubule depolymerization. KIF2C phosphorylation by AURKA or AURKB strongly reduces KIF18B-binding. SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Cytoplasm, cytoskeleton. Note=Present predominantly in the nucleus and to a lesser extent in the cytoplasm of interphase cells. During mitosis, found to be closely associated with astral microtubule plus ends emanating from the spindle pole during prometaphase and metaphase. TISSUE SPECIFICITY: Shows a prominent expression in the amygdala. DEVELOPMENTAL STAGE: Regulated in a cell cycle-dependent manner. Not expressed in the G1 phase. In G2, sequestered in the nucleus. Maximal levels seen at late G2/M phase and early prometaphase. Degraded at the metaphase-anaphase transition (at protein level). SIMILARITY: Belongs to the kinesin-like protein family. SIMILARITY: Contains 1 kinesin-motor domain. SEQUENCE CAUTION: Sequence=AAI36591.1; Type=Erroneous initiation; Note=Translation N-terminally extended; Sequence=AAI44272.1; Type=Erroneous initiation; Note=Translation N-terminally extended;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
